Synthetic, spectroscopic, thermal, and structural studies of antimony(III) bis(pyrrolidinedithiocarbamato)alkyldithiocarbonates

Abstract

An account of the synthesis, spectroscopic, thermal and structural behavior of antimony(III) bis (pyrrolidinedithiocarbamato)alkyldithiocarbonates is pre- sented. The reaction of antimony(III) bis(pyrrolidinedithio- carbamate) chloride with potassium organodithiocarbonate in equimolar ratio yielded the corresponding mixed deriva- tives of the type ((CH2)4NCS2)2SbS2COR (where R = Me, Et, Pr n ,P r i ,B u n , and Bu i ). These newly synthesized com- plexes have been characterized by physicochemical (molecular weight determination, melting points, and ele- mental analysis), spectral (UV, IR, far-IR, NMR ( 1 H and 13 C)), thermal (TG, DTA, and FAB ? mass), and structural (powder XRD and SEM) studies. Analytical studies leads to purity and structural properties of the synthesized complexes on the other hand powder X-ray diffraction and SEM studies show that multiphase, polycrystalline, and rod-shaped complexes have been formed having nanorange crystallite size and monoclinic crystal system.
